Seen over at Designboom, Kononenko's long pivoting stainless steel arm resides in the shower and can be brought down to service the sink, held in place by a counterbalance. An interesting aspect is how the water flow can be changed depending on its position: in the shower, water comes out as it would out of a shower head; in the sink, it pours out as per usual.

The doubling of functions into one bathroom fixture means less materials and perhaps less water would be used in the same room than in conventional practice. The steel arm is intriguing, though we wonder about the effectiveness of all that wood in such a wet environment (maybe it's for demonstration/modelling purposes?), and if a graywater-purifying function might be added to make it even greener. More over at Julia Kononenko.
